I kinda have the same problem when I alt+tab to swich windows. When I go back it's all black, only audio. I tried waiting several minutes but it doesnt come back. I had an older version of OpenRCT2 and it worked just fine. I now downloaded the newest version 0.2.6 and it f*cks up if i toggle windows. Any fix for this? Thanks in advance.
Windows 7 Ultimate, 64bits.
