Issue I346 [80,med-high,resolved] Mouse remains locked in window upon task switching with CTRL key down. Reported by jasons-2007-01-10 Description: If the CTRL key is down in SIMION and the task switches, the mouse may remain locked inside the SIMION window. This can occur if you press CTRL+ALT+DELETE to open the Windows Task Manager. Reason: When CTRL is down, SIMION locks the cursor in the Windows for scroll effects. This lock was not being released upon task switching. To reproduce: Example #1: Enter View or Modify screens. Click on main outer part of window (not center graphical simgui part) to place focus on it. Drag mouse into graphical simgui part. Hold down CTRL key. Note: mouse is trapped in window. With CTRL down, press ALT+DELETE also to bring up task manager. Note: mouse is still trapped in window, even if you release CTRL. Original report-jasons: Twice now, I have had SIMION open on my desktop while locking my computer to walk away (<ctrl><alt><del>). When I have come back and logged back in, my mouse pointer is stuck in an invisible frame in the SIMION window. So, I cannot get to the minimize or close button or anything else to get out of it and have to <ctrl><alt><del> to restart. For now I will make sure that I minimize the SIMION window before locking my computer. Note: ALT+TAB sometimes helps to remove this lock. Affects 8.0.0-8.0.1 Resolved in 8.0.2.
