hello out there! thanks for coming to my rescue! nope, not using the shift key. I am using a usb laptop mouse... and it happens with both of my wacom tablets, with mouse or pen.
I've been searching all night on the web for answers... I deactived sticky keys.. I tried using a list or icon mode then holding the shift key while opening the thumbnail mode.... ( found that re: missing file names, ..don't have that problem)
I have deactivated the keypad, and reactivated the touchpad.... it does the same thing! I have reset all the clicks and speeds many times. the frustration level is high! I have tried squirming the cursor up between the pics hoping it won't touch any of them.
I do have the cursor set for one click, and it highlights the file by just passing over, no click.
my desktop is set up that way with no problems...I use the control key all the time!
I sure hope somebody can solve this mystery.
