Mouse not working in edit mode

Question

I have version 4.0.1 on a Windows 95 machine, and I am having problems editing any VI. If I click on an item nothing happens, I cannot move it or delete it. I can add items but once they are placed, I cannot do anything to them using the mouse. For example, I can place an indicator on the front panel, but once it is down, I cannot move it or select with the mouse. If I right-click on it and hit 'Find Terminal' it will select the item in the diagram, and from there I can move it with the arrow keys or delete it with the backspace key, but once I click away from it, I am powerless again with the mouse. This makes it very difficult to move items and especially place wires.
This happens for VIs other people have written and VIs I create myself. If I double-click on a SubVI, it will open that SubVI, but single-clicking does nothing.
Thanks

Guess what - it's broke.
For what it's worth, LV 8.x should be able to open VIs saved in LV 4 and run them without problems. You might get all kinds of notifications about changes that were made and if you're using some hardware stuff, it could potentially break, but it should basically work.
That said, you will need to test it after porting to see that everything still works the same.
Another point to consider is that the environment in LV 8 is somewhat different from that of the older versions. However, if you've only been doing this for a couple of months, you should probably be fine.
By the way, I suppose that you might be able to use LV 4 on a newer version of Windows (at least if you're not using any magic hardware and maybe even in that case). You might wish to talk to your local NI office about this.
