WinSetState not working (but think its the programs fault)

Hi guys,

I have a program that when minimised to task-bar an using WinGetState returns 37. Maximised, enabled and exists?

Using WinSetState ("[CLASS:TfrmDesktop]", "", @SW_MAXIMIZE) returns 39. Maximised, enabled and exists and visible?

But will not maximise the window.

However 39 is what it normally is  when maximised and using the program

Just using @SW_RESTORE = 7 but does not open window (obviously)

and using @SW_RESTORE then  @SW_MAXIMIZE = 39 but then cant minimize.

and using @SW_RESTORE then  @SW_MAXIMIZE then @SW_ENABLE = 39 but then cant minimize.

Tried this and nothing WinMove("[CLASS:TfrmDesktop]",0,0,@Desktopwidth, @DesktopHeight)

Really strange as not sure what else to try.

Thanks guys
