To debug spotter you should first open it in debug mode. The simplest solution is to use��GTSpotterGlobalShortcut class>>openGlobalSpotterDebug
When not in debug mode spotter has an exception handler that captures all exceptions and write them to transcript.
I remember we fixed a while back some bugs related to styling caused by the fact that styling was done in a background process.
Though a quick look on the changes introduced in��50064 doesn't reveal any style related change that could cause this issue.
Cheers,
