An increasing number of users are complaining about WinMx behaving odd after a few days.
Switching between the screens getting more and more difficult, complete white screens and in the end no other solution than restart WinMx.
Temporary solution is rightclicking WinMx's Blue bar on top and select restore all windows.
A way to make the white screens occur after a longer time is reducing the scrollback limit in the chatwindow(s)
All is caused by a memory leak in WinMx.
The use of MxMonitor with auto whois switched on will make it worse.
Well, there is a solution for this problem.
Find your winmx.exe
rightclick it and select properties
goto compatibility tab and tick no visual scemes.
click ok.
Next time you launch WinMx it will be effective.
For the people who look very close, you will notice the corners of the windows to be a little sharper.
