After following Konstantin's debugging suggestions, I thought I would try to replicate
the issue on my own computer. My hope was that I could provide instructions for
replicating the bug so that the MIDAS team could try debugging things more easily.

Dear all,
I'm writing a very simple device driver starting from the nulldev.cxx

The "multi" class driver takes care of that. It properly calls the SET and GET functions
with the correct index. The code for that is in multi.cxx:105:

It would be nice to have MIDAS notifications pop up outside of the browser window.
To get enable this myself, I hijacked the speech synthesis and I added the following to mhttpd_speak_now(text) inside mhttpd.js:

people using Edge/Chrome/Safari/Opera saying "it's not working on my specific browser on version x.y.z". So I'm only willing to add that feature if we

Ok, I implemented desktop notifications. In the MIDAS config page, you can now enable browser notifications for the different types of messages. Not sure

Another problem while using odbedit.
I tried the batch mode of "odbedit". I created a key as "/A_Str" by mistake and
