In Process Guard GUI, the lower window with the program list cannot be increased/decreased after making a change to a program parameter or add/delete a program. The up/down arrow does not appear when hovering over the bar to permit increase/decrease size. The only way I have found to get this option back is to close PG and then reopen it.
Hi siliconman01, If you have a highlighted item in your list just press escape or F5 to get control back of the centre bar. It's not a bug but a "feature" Pilli
