Mouse passing over SuperDom caused freeze

[crokusek]

Nt8 was running fine for awhile unattended, then I come back and start adjusting a few charts and it froze. The stack trace shows something about the mouse passing over the SuperDOM. There were no open orders. I have no charts with more than one data series or cascaded indicators (noted since chasing a different issue).

Posting in case others hit or if the developers would want to analyze the stack trace. I have no other useful information.

Thanks,
Chris
