I'm getting a freeze with 126.96.36.199 in the hangar. After clicking the "To Hangar" button, the hangar will load and run for for a few seconds before freezing with a "busy" mouse cursor, and without clicking the mouse or any other controls. If I press any key or mouse button the standard "application has stopped responding" requester pops up. The previous release worked fine, and the skirmish mode still runs great, it's just the hangar apparently. This is on a laptop running Windows 8.1 64 bit and Intel HD4000 integrated graphics (Core i5 3230M CPU.)
*UPDATE* It works fine if I set XWINGALLIANCE.EXE to XP SP3 compatibility mode, so at least it's back up and running.
You are a godsend! I was having exact same issue and was making game unplayable but once I set Compatibility Mode as stated above all seems well now!
