Publisher 2 falls over constantly in Windows 11. Copying Master pages, adjusting table borders, placing graphics, changing stroke width, double-clicking - seems literally anything can trigger a crash. Sometimes it will save a recovery file, sometimes it just quits. The issue is so ubiquitous that there's no real pattern - so hard to say what exactly it is that causes the issue, but it is near-constant and makes working very difficult, not least because the files don't seem to be backwards compatible with version 1!
For info, I'm running it on an old Dell m3800 (Core i7-4702HQ, 16GB RAM) which ran Publisher v1 perfectly fine. There is no difference if I use embedded Intel graphics or the discrete Nvidia K1000M graphics card. Designer 2 works fine on the other hand...
