This is more than likely a Windows bug but I wanted to call attention to it here just in case it's some new thing they're doing that actually breaks the way mIRC draws its window.
OS Build: Windows 11 Enterprise Insider Preview Build 27695. (The Windows Canary Build, latest as of September 17th)
Upon resume after locking Windows + monitor sleep, the mIRC window is unresponsive and is usually fully white. Although sometimes it shows text but hasn't updated. Closing the window via the title bar is unresponsive, but right clicking the icon on the taskbar and closing usually works.
Reloading mIRC is fine, no other issues after closing and reloading.
This occurs after the monitor goes to sleep for an extended period of time while mIRC is drawn on the screen if I've locked Windows and left it there. If I minimize mIRC first, this does not occur.
If it matters, it's an Nvidia graphics card on the 561.09 driver. Although it was occuring for a few revisions before that.
Like I said, probably a Windows insider bug but it only seems mIRC is affected by this for me.
