For some reason when I use this, if I switch from any algo, to another, and back to original algo (doesn't matter which), the original algorithm will not mine. It winds up in benchmark mode for some reason (generates shares, but none are submitted). This is fixed if it closes the window and restarts (maxtime reached).

Anyone else experience this issue? Don't like missing 30 minutes of hashing everytime I switch an algo

Which miner are you using? I wonder if there could be an issue with the new miner instance re-initializing the video card before the previous instance has fully spun down.

Please see if you can recreate this behavior using the start buttons on the individual algorithms. If you hit the start button for an algorithm and another one is already running it will do a stop on that existing one and start the new one immediately, just like when an algorithm switch occurs. If you can trigger the behavior, then try doing a stop, wait for a second, and then hit the start button for another algorithm. If the first test triggers the problem and the second doesn't then it is likely a re-initialization issue.

A workaround I can suggest for this is to find one of the sleep utilities on the Internet. Do a search on "sleep.exe" and you'll find a ton of them. Run your miner from a batch file and put a sleep in front of starting the miner for however long is required based on your tests above. This will let the card calm down before the new miner hits it again.

Hope this helps.
