Dropping files to fullscreen apps through mission control results in app folder opening and in some sort of task switching madness

Question

In Snow Leopard I got used to attach documents in mails by dragging and dropping files from the desktop to the message window. To do so  I used active corners (spaces, exposé). Now, with Mission Control in Lion I've tried to keep that workflow but this leads me to an awkward problem. To reproduce it in my computer I do the following:
Pick up a file from the desktop --> drag it to lower right corner (opens mission control) --> drag it to full screen mail space, press space to switch (applications folder opens inside mission control), and a lot of apps too (those the cursor hovered).
At the same time, mail full screen window opens (as waiting time selected in finder preferences for triggering is short), then Lion turns crazy entering in some sort of spasmodic task switching mode, which lasts after I find some clear space to drag the file back in the desktop.
Did any other user  experience something similar? Is there something I could do to help to fix the problem?
Thanks for you answers.
[Edit: Ok, so I started trying with other apps and it turns that every time I drag and drop any file to a fullscreen app in mission control and use the space key to open it, I get a similar behavior. I did it in Scrivener and it resulted in photoshop and itunes opening,  Scrivener vanished and but left an empty (like dashboard's) desktop.]

Hi,
Thanks for your reply.
>>Running bootcamped Win7, yes power consumption is more, a lot more,....indications are no.
Sorry, can you clarify on this one - do you mean the power consumption is more DURING the use of Windows, or ALL of the time (even when using the Mac as normal with OSX).... also what did you mean by indications?
>>From the parameters of what you say your use would be, Id recommend the I5 with 8gig of ram. the 12 hour >>batt. life is only rated for the 13" on the I5, ....not the I7.   
Sounds like my first guess was about right - and good point about the battery life - as that is something that's quite important to me!
>>The "switch" is extremely easy. Ive seen grandmothers switch to a MAC and have its 'everyday use' >>conquered in under a week. So, you should have no worries, its extremely user friendly, no worries of virus, >>etc.
Glad to hear I've done more research and already seen a few features I can see myself preferring a lot more to the Windows system!
>>As a former computer repairman, Ive owned nearly 200 diff. laptops (many were free, or Franken-computers >>built from parts) and I can honestly say the Macbook AIR is the finest piece of beloved hardware Ive ever >>owned by a mile.
>>Many people incorrectly see the THIN nature of the Air and incorrectly conjecture its "less than" a full laptop, >>but the contrary is the case.
Nah, I don't associate size with performance - especially these days, everything is getting smaller. My concerns are really just about whether to upgrade for extra performance, and using the OS - once I have those nailed I am pretty cofident the hardware will perform well.
>>Additionally the AIR is the only Mac that has 802AC wifi, new Haswell cool-running processor, and extremely >>long 12 Hr. batt life on the I5 13" configuration.
Yeah that battery life is one of the big sellers
Cheers for the tips,
Danielle
