It could be a Windows XP specific problem.
Here's a pre-release version of RadioBOSS 4.7.3:
http://dl.djsoft.net/radioboss_setup_4.7.3.0.exe
There were some fixes and improvements* made as long as it will generate a detailed bug-report**. So it will either stop crash, or if it doesn't - please send a bug report.
* Changes in 4.7.3 (may be changed upon final release):
- tracks are launched faster
- TrackTool loads faster
- TrackTool and SegueEditor use much less memory for operation
- wizard for encoders setup
- Windows Media Server support (it's not complete yet...)
- integrated broadcasting server
** How to send a bug report:
- start RadioBOSS
- click Settings->Open Settings folder
- a folder will open, you'll see "bugreport_nnnn.txt" files - one file for one error. Sort them by name and send couple of last ones. Once we have the report(s) - the bug will be fixed for sure
Thanks for cooperation.
