Strange "Return" message in log

I have a Windows web app that generally works OK. But lately, I’ve noticed that when I run it from the debugger, I get an endless stream of messages in the Xojo console that look like this:

Return 028F0BF8

The number increments by 32 with every message. I’m not calling System.DebugLog with this string, and I can’t for the life of me determine what’s causing it.

Any thoughts? Thanks!

Do you have any Plugins / 3rd Party controls?

Just the MBS ones. This is Xojo 2016r1.1 with MBS 16.1 plugins. No 3rd-party controls.

please update. We had that long ago and it was fixed.

(just a debug message I forgot to disable for release)

Thanks Christian. That solved the problem!
