In LabVIEW 2023 Q3, Quick Drop can take between 1 and 3 seconds to appear after pressing Ctrl-Space. This has been reported to LabVIEW R&D as Bug 2468882.
As a workaround, replace the following VI with the one attached to this post:
[LabVIEW 2023]\resource\dialog\QuickDrop\QuickDrop Log Keyboard Shortcut.vi
Mass compile the folder containing that VI, and you should find that Quick Drop is quick again.
So the big question is, in which release will this bug be patched?
I don't know. The patch will likely be similar (if not identical) to the patched VI I've attached above. I'll post on this thread when there is an official patch and/or upgrade that fixes the issue.
Many thanks! After 20 minutes of using 23 Q3, came here looking for a solution for exactly this.
This bug is fixed in LabVIEW 2023 Q3 Patch 1, now available for download in NI Package Manager.
