This issue occurs when I use the Rockbox Utility to upload new themes to my Clip+.
I start with my Clip+ connected and identified by Rockbox Utility. On the Extras tab I click "Install Themes". This gives me I get the list, and I select my desired theme, and click Install. The progress log shows that the theme was installed successfully. However, when I unplug my Clip+ and go into the Settings -> Themes Setting -> Browse Theme Files, the new theme is not in the list. I checked the Themes and WPS folders in the .rockbox folder, and indeed the theme did not copy over to my device.
I am running Rockbox Utility as an administrator. Also, I can manually download and copy over the theme and it works just fine. However, Rockbox Utility doesn't seem to copy it over.
Any ideas about what I doing wrong?
