How do I fix a script run-time error coming from my HUD every time I wear the HUD, or login or teleport?

You might get a script run-time error (either a stack-heap collision error or a bounds check error) when you login, or when you teleport.

This is the Second Life platform being funny again.

First, make sure the error is coming from your HUD. You can do this by remove all other attachments, and teleport or relog. If you still get the message, the error is coming from your HUD.

To fix, simply do a smart reset.

If you have HUD v4.x - SL has borked it so that Smart Reset doesn't work properly at times. To fix, just update to the v.5 HUD.
