[LAVA Cross Post] CTRL+SHIFT+Alpha Shortcuts don't work in LabVIEW

[JackDunaway]

Cross-post from LAVA: http://lavag.org/topic/15619-ctrlshift-shortcuts-sometimes-not-working-in-labview/

Bug Synopsis: CTRL+SHIFT+Alpha shortcuts do not work in LabVIEW. Most notably, CTRL+SHIFT+Z, CTRL+SHIFT+E, and CTRL+SHIFT+S

Test setup: LV2012 32bit with f1 patch running in Win7 64bit inside a Parallels 8 VM in OS X 10.8.1

To summarize the testing I have tried:

• Many different LabVIEW, Guest OS, and Host OS combinations all fail, including:
• LV2012f1 32 and 64 bit, and LV2009 32 bit
• Win7 32 and 64bit, and also WinXP x64
• Parallels 7 and Parallels 8
• OS X 10.7 and 10.8
• Capturing the keyboard by the VM
• Twiddling every keyboard setting possible on Parallels, Guest, and Host
• Reinstalling keyboard drivers
• Plugging in a known-good keyboard that works on a native Windows machine
• Deleting LabVIEW.ini and letting it regenerate
• Remapping the shortcuts from, e.g., CTRL+SHIFT+E to CTRL+E - in this case, "Show in Project" works, so this might indicate it's a problem registering the shortcut press, not invoking the action itself.
• Sending the keystrokes via on-screen keyboards from both Guest and Host
• Sending the keystrokes via SendInput from user32.dll WinAPI
• Testing every imaginable combo of FN, CONTROL, ALT/OPTION, COMMAND/CMD, SHIFT
• Reinstalling VMs from scratch and reinstalling LV
• Here's a kicker: CTRL+SHIFT+Alpha shortcuts work fine on other Windows programs (I've tried 4 different programs, including Chrome, Notepad++, Paint.NET), yet it does NOT work for VIPM with CTRL+SHIFT+C. This means that the only two programs where the CTRL+SHIFT+Alpha bugs exist are both LabVIEW-related.
• Here's another kicker: It's only CTRL+SHIFT+Alpha shortcuts with the prob - CTRL+SHIFT+3 properly toggles grid alignment, and the "Tools >> Options >> Menu shortcuts" will register any CTRL+SHIFT+Non-alpha shortcut; it just does not respond to the CTRL+SHIFT+Alpha shortcuts.

Any new troubleshooting ideas are highly appreciated; please feel free to jump in here or on LAVA.

Tried creating a fresh Win7 VM using VirtualBox rather than Parallels, and the CTRL+SHIFT+Alpha shortcuts work just fine. Perhaps this indicates a Parallels-LabVIEW incompatabilty?

I have begun a support thread in the Parallels forum also: http://forum.parallels.com/showthread.php?p=639396#post639396

Still well and alive in Parallels 9 and LabVIEW 2013 SP1. Of course I could upgrade to the latest versions to check whether things have gotten any better.

Any news on that?

@Mellroth figured out the solution 🙂

Great. I had checked the thread but couldn't make sense from the answer.

Thanks for the detailed walk-through. That solved the issue.

What baffles me is who flagged your post as an answer before I had a chance to...
