I saw an other post in which Ghister told to add the :
DeviceChange=0 to the wincmd.ini. I did this already, but I keep having the same problem.
So each normal hard drive of my machine is no problem, but for every network drive the panel starts to blink. And then not all files but some of them and mainly the blue selection bar blinks.

Is this a problem with my network card driver? Or a setting in the TC7 configuration?
Hopefully some of you has a solution.....
