Thanks SiGfever for your testing.

This doesn't happen in XP 32 bit. When the tray icon is incorrect, is the pop up temp information correct?

I re-wrote the tray icon code and I'm hoping it cures the Vista problems. If not then I guess I'll be looking for a plan B.

This is version 2.53. Download and copy RealTemp.exe into your main RealTemp directory.
