Hi David,
You have this implemented in new version 1.0.35.311 RC6, which I'll upload this afternoon.
Since we still don't have a Preferences interface, you must edit the configuration file, namely:
~/.config/PleiadesAstrophoto/PixInsight-1.0.conf
(Windoze users, this involves messing with the Windows Registry with regedit.exe; do that at your own risk)
Locate the following keys:
Preferences\MainWindow\AnimateMenu
Preferences\MainWindow\FadeMenu
Preferences\MainWindow\AnimateCombo
Preferences\MainWindow\AnimateTooltip
Preferences\MainWindow\FadeTooltip
Preferences\MainWindow\AnimateToolBox
These are boolean keys, so setting them =false will do the job.
In addition, there's also a new boolean key that may be of your interest:
Preferences\MainWindow\DesktopSettingsAware
Thank you.
