If you report a problem with the GUI, mention which GUi you are using (there are several) and please do not refer to a problem with JKDefrag because JKDefrag is made by Jeroen Kessels .. and the GUI versions are created by other people
OK, I am using your excellent GUI. Version 0.6.
When I unzip your GUI to C:/program Files/ JK Defrag I right click the JKDefragGUI.exe and select "pin to start menu". The short cut that is created when I do this doesn't work properly. When I launch JkDefrag with this short cut it create a bunch of files in C:/Documents and Settings/User Name. The files created are duplicates of the files I unzipped into the program folder. Even after deleting the new files created in C:/Documents and Settings/User Name they get re created every time I launch the program from the start menu short cut.
I fixed this by removing the start menu short cut. Than I went back into the program folder and right clicked the JKDefragGUI.exe and selected create short cut. This created a short cut in the folder. I than right clicked that short cut and selected "pin to start menu". The start menu short cut now works properly.
