I will check whether it shows the same behaviour as the full version. + Stephan + + ------- Additional Comments From sbuehne(a)web.de 2002-05-31 13:51 ------- + I have checked the free demo version, which shows the same behaviour. You + can + find it under + http://www.signalsoft.de/services.htm + Download "Download demo Köln Hbf (527 kByte)". Extract it into a subdirectory + and run the application simply with the command "wine kolndemo.exe" + The application stops on the initialization screen with the same error in the + strace-log as the full version. + Stephan

I will add my stuff tonight and try to post the results tomorrow.... + + all of this information is against the current mouse.c, not rev 1.2 which is + the first version with this problem... \ No newline at end of file
