"Invalid Monitor Handle" after changing screen configuration

[j10k]

Describe the bug I have set AutoScreenshot to capture a screenshot of all monitors. After switching monitors, e.g. by connecting to a dock, subsequent screenshots fail with "Invalid Monitor Handle". Additionally, the "Used monitor" dropdown in the configuration dialogue is disabled/greyed out and set to "monitor 1". Restart fixes the problem

To Reproduce Steps to reproduce the behavior:

1. Enable auto capture of all monitors
2. Change monitor configuration. Note that this does not occur for all changes, even when the same monitors are used
3. At the next time interval, an error box saying "Invalid Monitor Handle" appears in the background.
4. Upon opening the config dialog, observe that the Used monitor dropdown is greyed out.

Expected behavior AutoScreenshot should handle changes in the monitor configuration and update the monitor handles after changes.

Screenshots n/a

Version 1.7.1

Can't reproduce on Notebook with Windows 7 and plugged additional monitor. I tried:

• connect/disconnect extended monitor
• change orientation
• change primary monitor
• change order

Could you please describe your monitor configuaration and what action causes a problem? Take screenshots and maybe video also may be useful.

I only saw that program doesn't update listbox when monitor configuration has been changed.

Thank you! I was wondering how to provide debug information, and will reopen this issue if it persists.

Hi, unfortunately the issue is only partially fixed for me (not sure whether to reopen the issue here or open a new one): I have set AutoScreenshot to screenshot all monitors. After changing the display configuration, however, the configuration reverts to "primary monitor". Steps to reproduce:

1. Have two displays. Set AutoScreenshot to "all monitors". Take a screenshot.
2. Disconnect second display. AutoScreenshot shows disabled display dropdown set to "all monitors". Take a screenshot.
3. Reconnect second display. AutoScreenshot shows enabled display dropdown set to "Monitor 1 - primary".

Expected Behavior: Keep screenshotting all monitors.

It will be better to create new one.

After changing the display configuration, however, the configuration reverts to "primary monitor".

You can change it manually.
