If there are any experienced users of TortoiseHG here I'd like to ask them if they know of this problem and a way to fix it:
Right-clicking a file in the TortoiseHG UI and selecting Add or Forget popups a dialog telling me: "*Filename* not under root *Folder*". If I use the equivalent context menu from Windows Explorer the commands work and refreshing the TortoiseHG UI shows me the changes. Web searches produce no useful information on this problem. I have no idea what started this, as I haven't run any upgrades or moved folders or done other suspicious things, the problem just started one morning a couple of weeks ago. It's driving me barking mad. Greg K
