Change in GPS coords in LR 1.4.1???

Question

Has v1.4.1 had a change to the GPS metadata panel? I use RoboGEO to upload geodata from my GPS unit and then tag the images prior to importing into Lightroom. Previously by clicking on the GPS button in the Metadata panel Google Earth has opened up and the location my images(s) was taken from has shown up perfectly.
However, upon return from a shoot yesterday I have tried the same operation and sequence as I have always done but with strange results. The only thing that has changed in my workflow is the upgrade to version 1.4.1 and so can't help but feel that my problem lies somewhere in that direction.
For instance, checking on my GPS unit for a particular waypoint that I have saved shows this to be 48°33'1150" N - 8°59'1442" E. When transfering from the GPS unit to RobOGEO exactly the same data is shown to be stamped to the images EXIF data. I have even entered these coordinates manually with the same results.
Back in Lightroom however, the coordinate data is different and of course when opened in Google Earth a completely different location is shown. The same coordinates as stated above show as 48°19'54" N - 8°35'29" E in the Lightroom panel.
Has anyone any idea whatsoever as to why this should be as this is now becoming very frustrating? Just to repeat, I never had this problem until upgrading to v1.4.1 and that is the only thing that has changed in my system or workflow.

Yes sure. On my Garmin Map60CSx I use the 'Mark' button to set the Waypoint from where I have taken the shot. I then change the name that Garmin automatically sets for it to the image number - so for example if the image number is IMG_001.CR2 then I name the Waypoint number to 001. This makes it easier to tie up Waypoint to image later in RoboGEO as both will be unique. Before saving the Waypoint I use the Avg (Average) button which calibrates or fine tunes the Waypoint any number of times. I usually let it run to around 50 times noting how the +/- value changes. Once it has steadied I then save the Waypoint. Obviously the final accuracy of the saved Waypoint will depend upon the type of terrain (clear sky or overhead trees etc )one is in but generally speaking I have been very well satisfied with the results.

The time the Waypoint was saved plays no part in the issue which is why I prefer this method over and above the track method.
From the File menu in RoboGEO (or using Stage 1 in the left hand panel) I import the CR2 images (or sometimes DNG's if I've converted them first). When the images are imported they will be listed in the main window from which I highlight the first image - say 001 using the example above. Moving to Stage 2 in the left hand panel and with the GPS connected to the computer I click on 'from GPS waypoints'. This opens another window in which all the saved Wapoints on my GPS are listed. I then click on Waypoint 001 to match the image 001 which then lists the coordinates for that Waypoint in the main window alongside the image. In Stage 3 I then click on 'write location data to EXIF headers' which then stamps the coords into the image. Job done and pretty simple and as said previously my preferred method because setting and averaging a Waypoint I find to be far more accurate which in your own experience can be 100 feet or more out. Time is not an issue here because one is quite simply matching image to Waypoint. The time the Waypoint is set doesn't enter into the equation only that one doesn't move away from the original place of course. This differs to your chosen method in so much as there are many areas in which time DOES play a part and which is prone to several areas of innacuracy. For example, if your time in your camera and GPS are not PRECISELY matched then this will obviously induce error. RoboGEO is matching the 'time' the image was taken (from the images exif data) to the nearest track point set at that time. If your camera and GPS times differ by 1 minute .........well one can cover a lot of ground in that time. :-)
