apparently sometimes when a screen goes away there is a perios in which the panel window is still alive but its m_screenToFollow is already been deleted, access to it may have to be guarded everywhere *** Bug 373296 has been marked as a duplicate of this bug. *** Thank you for the report. As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thank you.
