I recently updated to V1R3.2 X64 on my Windows 7 64bit PC. I now get artefacts at the top of the screen intermittently. Also if I click on a line it does not "highlight" or change in any way. If I try to draw an arc it does not appear until I press enter. I'm running an ATI Radeon HD 5450 graphics card with the latest driver. On another machine running an Nvidia graphics card V1R3.2 X64 runs fine. Thanks Will Beavor
