LSL Helper feature: say^textstring "white chat" fail on Win 11

[stonejohnson]

I have run into a problem with Radegast 2.41.357, concerning the LSL Helper command where you InstantMessage "say^textstring" to yourself and then it puts it in nearby "white" nearby chat,

e.g., using an avatar attachment that executes

llInstantMessage(llGetOwner(), "say^textstring");

Under mono in ubuntu linux this works just fine, but a friend using the Win version in Win 11 finds it just doesn't work - is this a known issue? Sounds like this feature works fine in Win 10, too!

Thanks! Stone
