I just purchased curtains and was making my first set up. I chose to edit an existing theme. All was going well until I was unable to change the blue line at the top of my taskbar. First I tried to use my custom image hoping it would be automatic. Unfortunately that caused half of the taskbar to change colour. I then tried to get my taskbar back by starting the process over. Unfortunately, without warning the taskbar disappeared except a flashing thin line. I couldn't access the taskbar or the start menu. I had to use ctrl alt del to sign out and reboot. After reboot, the problem remained and start menu showed in task manager as very high memory usage.
The only way I managed to fix the situation was to go into control panel through right clicking on the desktop and uninstall curtains. The uninstall gave me the option to reset my settings. This solved the problem but I lost all of my previous windows settings as far as desktop image and colours, etc.
There is obviously a major flaw with this program that needs to be fixed.
I have used fences for quite a while with no issues at all and I am a competent computer user. I would like a refund for this program as it is obviously not safe to use.
