Suddenly slow

[kboy421]

I have a smartphone with WM6 and it has this quirk where it suddenly starts responding very slowly. Rather than tapping a selection, I have to hold it for about 2 seconds. Writing is very difficult because I have to hold the stylus down for about 2 seconds, then move it to write the character. It can happen when only one program is open. I can restart the device, and that may fix it, then it starts again. I have used SK Tools to free up ram and sometimes that helps and sometimes it doesn't. I have 8.33 MB free program space and 116 mb free storage space. Any ideas of what to do? Thanks for your help.
