My computer is running all the time, but I restart MyPal from time to time. About six weeks after a fresh start, the MyPal window suddenly becomes transparent, leaving only the title bar at the top visible. Restarting MyPal doesn't help; only restarting the computer helps. When the MyPal window is transparent, I can click the address bar and enter the website address. The website loads, as shown in the title bar, but MyPal is practically unusable. I have MyPal 74.1.3 32-bit. The problem also occurs on older versions of MyPal, but does not occur on MyPal 29.3.0. My GPU: NVIDIA GeForce GT 430.
