--- Comment #25 from Michael Setzer II mikes@kuentos.guam.net --- I can only report what I see. And only difference is the updating of winehq Generally when I install a new winehq update I run wine notepad as a quick test afterwards to have it do the wine updating process.
On one machine, I then gave the seh errors and only adding the +heap option would get it to work.
Pegasus is actually the only windows program I run.
Then just noted the problem on my main notebook when I upgraded to the 10.10 that the Pegasus screen was all messed up after the upgrade. Downgrading to 10.9 fixed it to normal..
I had also tried going to winehq-stable and that works fine. Also, when back to Fedoras Wine installation and it also worked fine, but did notice that it was a staging version like you mentioned.
Don't know why it worked fine up to 10.8, but now have had problems with 10.9 and 10.10.
Thanks for your time. Original notepad issue was only on an Acer Aspire notebook, but Pegasus issue is on my Dell Notebook. Both older machine.
