Bug - don't use xlock

Hi, I use xlock every now and then. It is not funny returing to your machine in your computer lab where lots of people have access to the machines, seeing your desktop unlocked displaying this message: bash:# > xlock X Error of failed request: BadColor (invalid Colormap parameter) Major opcode of failed request: 84 (X_AllocColor) Resource id in failed request: 0x0 Serial number of failed request: 16289748 Current serial number in output stream: 16289748 There is Version: XLock version xlockmore-5.15 running, it is SuSE Linux 9.3. I have no idea what animation ran within xlock because it was already unlocked. Sincerely, Robert.
