Ever since I upgraded to a Nec 3090, 30" monitor, I have problems with importing in LR 3.3 3.2 etc. This problem does not occur on LR 2.x or 1.x.
If I am running the monitor at 2560 x 1600, and I hit import. LR will freeze totally. I can't recover the system without a total power off. If I drop the res to 1900 x 1200 on the same monitor it works fine. The freeze is where LR3.3 would open the GUI drop down where on the older versions of LR you just get a windows dialog box.
I have noticed that if I minimize the LR window to less than 1/2 of the screen on import then it works at 2560 x 1600. However this is a pain.
Usually after I have finished importing, I can take the window back to full screen.
System is XP 32 bit, 8 Gb of ram. Video Nvidia GEforce 450.
