Heidi freezes completely when using multi-monitor setup

Hello, I use the last version (12.11.0.7067). I have a laptop + 2 screens. When I launch Heidi, after the screen of connection, it appears on the screen of my laptop (the smallest). When I try to put the Heidi's window on the other screens, it blocks immediately the application, as soon as it starts to enter in one of the two other screens. Nothing possible to unblock, except to kill the process (that indicate a very high use of power usage for Heidi).

If you're dragging the window while it is maximized on your laptop screen: You may try to restore ("un-maximize") the main window before you move it.

That way, you probably prevent a resize event during the move to the other screen. If the screens have also different DPI settings, there are even more events triggered.

Hello Angsar ! Thanks to you to reply (this Heidi SW is soooo good ! :-) ) Indeed, to move the main Heidi HMi, I reduce the window. But when I move this reduced window to one of the 2 other screens, as soon as half of the reduced windows is on the other screen, it blocks (and blocks most my others SW). I'm obliged to use the Task Manager, to seek Heidi in the running process list and to kill it.

(Despite the size of 2Mo, I can't suceed to post a screenshot...)

In that case I guess the DPI settings of these both screens differ, so the OnAfterMonitorDpiChanged event is triggered, which then triggers the OnResize event, which contains code which likely cause the freeze.

Please

• while the window is on the laptop, click Tools > "Reset panel dimensions"
• then resize the main window to a reasonable size, let's say roughly 1000 x 800 pixel.
• then move the window to your other screen.

If the freeze still happens, please report the DPI settings of both screens. You can look up the DPI settings in your system settings for the displays, where you also define their resolution.

Hurra ! By changing from full screen to reduce screen + tools and "reset panel dimensions", it works ! Thanks a lot, Ansgar !

(Congrat' to still use Delphi/Pascal ! I learned TP, at the beginning of 90's :-) )
