Version:           KDE 4.2 (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

1. When typing in a command in the "Command" text entry box on the New Task for a Personal Cron job, the focus is intermittently shifted to the other widgets on the GUI as I typed. For example, I tried to enter,  echo "this is a test"
and upon clicking the space bar the focus jumped to the Months widget and selected January.  
This problem went away after I set the cursor back into the command text box a few times when the focus jumped away.

2. After I created a personal cron job, I selected the job and clicked  the Modify button.  The "Comments" text box contained additional comments that I did not put in there, as follows:
 DO NOT EDIT THIS FILE - edit the master and reinstall.

my synching of tomboy dirs every morning at 2:00am

The last line, "my synching of tomboy..." is the only line I put into the comment box.

3. Also, when modifying an existing job, the original settings of the job are lost when entering the "Add or modify a scheduled task" panel. Only the command and comments (with the additional comments from #2) reflect the existing job.  The Enable and Run checkboxes, and the month/day/time/etc are all reset to nothing selected.  They should be set to the original settings of the existing job.
