Hi Rui,

Using the app from here:

http://www.masm32.com/board/index.php?topic=10892.0

I had that same problem, but I did not attempt to determine how to fix it because I seldom change my display resolution. My thoughts at the time were that the app should use EnumDisplaySettings to get a list of known-valid settings, and use one of those.

MichaelW,
                how are you ? fine, i hope.
Here is the example.
1. The prog starts at the resolution 800x600. Then we choose Definições->Change resolution and 1280x1024. What happen ? There isnt staus bar !
2. We close the prog (it is in 1280x1024) and restart. The status is there.
3. Change resolution to 800x600. the staus is there too
files below: screen3.zip (exe&asm), rsrc.rc, ecrã.exe
thanks

I did an example using enumdisplaysettings further down that thread using enumdisplaysettings.
