Ok Tempest, this bug i found happens a lot. Maybe 35% of the time? But it's VERY random too. Let me explain: (**fyi i'm using the latest version of InfranView) 1) I have MM (Marquee Magician) setup to launch a single infranview window for a mame marquee on my 2nd monitor. And that's it. The infranview window is 1650 x 490 2) My GameEx is setup w/ CPWizard. When I launch a MAME game CPWizard will show the CPanel on the 2nd monitor for that game for a few seconds like regular. Then after the CPanel goes away the screen refocuses/refreshes and will then will show the MM InfranView window with the marquee for that game. BUT about 35% of the time when it's "refocusing/refreshing the screen" it will do either one of these 2 things in the 2 screen shots i've attached for you below: I'll either get a file header error or that file window will pop up of whatever that window is pointing to. And it's really random which one i will get. I can launch 10 games successfully with MM and no problems at all. Then all of a sudden I will get this bug randomly. And it's not a particular game. I can use MM fine with a particular game 5 times then maybe on the 6th try get this bug. I know it's not a conflict with CPWizard because even when i disable CPWizard it still has this problem. Also, once this problem happens it keeps doing it for every single game afterwards and i have to relaunch GameEx to make it go away. It's kinda driving me nuts lol because I really want this to work flawlessly. Any ideas? **Also on a side note...is there a way to create a MM window and have it display a list of the high scores for that game? If they are enabled for that game? That would be too cool....
