i have the same problem to. After chosing the departure airport and selecting the aircraft i change to windowed mode to calculate the fuel with keroplan, also i check the settings in active sky (both the newest version). When i try to switch to fullscreen, the window goes black and the mouse pointer blinks when i turn it over the black window. Sometimes FS2004 ends with an error after a view seconds, or if not i klick on close and then the error comes. The Problem is at every Airport and with almost every aircraft but most with Eurowings A320 with flight 1 fmc.
The Error came the first time after uptdating fsuipc to the latest version. When Keroplan is off the error comes also but not so often. When i turn Activesky off, it makes no change. I have a full registered Version of Fsuipc, the last way i know is to put the external progs like activesky, fmc and keroplan on my second pc. But it makes for me no sense to pay 25.- Euro for WideFS when i don´t know that the problem is then solved, you know? Is there a chance to create a trial-serial for checking this or must i buy widefs? (Please not my wife kills me if i spend too much money for flusi !)
PS: My System: Win xp prof., fs2004, amd2300, gforce fx5200 (buuh, i know), via kt-400 chipset, 1 gb corsair ram. On this PC Flusi is the only game, no other games are installed, just office, nero, etc. drivers are the newest for all komponents, direct x new, all win-updates installed)
