I think this is related to caching, but sometimes when a map.refresh is called in our app, the error message "The directory is not empty" comes up and kills everything.
I have a google overlay and a few other overlays each using their own FileBitmapTileCache. The google overlay doesn't have a call to clear cache when it is defined, but the other overlays do.
Any ideas on how I can resolve this error? This doesn't happen every time, just occasionally, but certainly enough to make the app look bad.
Thanks!
