Hi. I'd love ToneLib, except that I'm experiencing a frequent and serious graphics glitch in the interface. The graphics keep getting badly corrupted (see screencap below). A momentary cure is affected by resizing the window containing the running program. However, the problem quickly recurs, rendering the program unusable until I resize the window again. I have only ever experienced this problem with ToneLib. Is anyone else experiencing this? Is there a remedy? TY Here are my system details: Operating System: Windows 7 Professional 64-bit SP1 CPU: Intel Core i5 2500S @ 2.70GHz 29 °C Sandy Bridge 32nm Technology RAM: 8.00GB Dual-Channel DDR3 @ 665MHz (9-9-9-24) Motherboard: Hewlett-Packard 1495 (SOCKET 0) Graphics: XB253Q (1920x1080@144Hz) 4095MB NVIDIA GeForce GTX 1050 Ti (Gigabyte) 64 °C
