Cross-post from LAVA: http://lavag.org/topic/15619-ctrlshift-shortcuts-sometimes-not-working-in-labview/
See the above post for more information - here's a synopsis:
CTRL+SHIFT modifiers are not working while running LabVIEW in a Parallels 7 virtual machine. This problem affects both LV2011 and LV2012. I'm not certain that this is a LabVIEW bug - could be an issue with my virtual machine environment or it's configuration - except that CTRL+SHIFT modifiers work in other applications on the affected VMs. It's just LabVIEW that appears to ignore shortcuts with the CTRL+SHIFT modifiers.
Any ideas?
