This is on Windows Server 2012 R2, screen resolution is 1440x900. Same code worked on other occasions and all the time on other Windows OSes.

Code:

LocalRegionObject = ( Region(0,0,1440,900) )

if LocalRegionObject.exists( Pattern("1494237247598.png").similar(0.75), 0.1 )

I have only been seeing this issue on Windows Server 2012 R2

[RaiMan (raimund-hocke)]

ok, forget my comment #2 --- simply wrong :-(

Based on more research in the net, it may be, that you have a memory problem in this case.

I am sorry, but I cannot help you.

okay thanks RaiMan
