In the quick view panel I zoom into an image either by double clicking the image or holding down the ctl key and rotating the mouse wheel. In the past I was then able to move the zoomed in image around so I could see parts that were not showing because they were outside of the zoomed in portion. I would move it around by left clicking and holding that down while I dragged the mouse. This no longer works. The arrow keys also don't work to move the image around.
Works fine here, just tried.
If you zoom in and left-click and hold, the file can be panned. No change here to IMatch 2023.
Just to be sure: You mean Quick View Panel, not Peek View? Peek View has no pan.
I do mean the Quick View Panel. It still is not working for me. What should I do to help figure this out.
No idea. Double-click to toggle between fit-to-window and 100% zoom. <Alt>+mouse move to zoom in and left-click and hold to pan.
I have tested this on 3 PC's and it worked on all of them. No similar reports from other users so far, so this seems to be something rather unique...
I have not used <Alt> + mouse move to zoom in before. I just tried that and it too doesn't seem to work. But the main thing that I have used fairly regularly is the left-click hold and then mouse move to pan. And that is not working.
I can't say for sure when this started but clearly since I updated to IMatch 2025, which was just three days ago. I started with 2025.1.6 and now 2025.1.8.
Works for me as expected. Tried it with different settings (docked / undocked panel, different window sizes). Always works as described in the help.
I've checked the revision control system for changes between 2023 and 2025 related to the Quick View Panel, but apart from new ribbons, icons and menus I don't see any. No changes in how the click-pan is handled.
Does it work in the Viewer?
The Quick View Panel and the Viewer use the same underlying image render, zoom and pan code.
It does not work in the viewer either.
This is really just a shot into the dark: Have you by any chance some kind of mouse configuration software running (e.g. like Logi Options+) where you can redefine the behaviour of some mouse buttons?
Ar, maybe, reboot your system once, in case something weird happened?
Not a shot in the dark.
I have had for years my "primary" (left) and "secondary" (right) mouse buttons switched. See the setting in Windows that allows for that (see attached screen shot).
I went ahead and unchecked the "switch primary and secondary buttons" box. Then in iMatch things worked as expected.
I would like to keep my primary and secondary mouse buttons switched and be able to pan in iMatch, as I have been doing for years. Is there some way to make that happen?
I have figured this out. It is a side-effect of a accessibility enhancement change I've made on September 22. 2024.
I've interpreted some API documentation wrong and explicitly checked with a system function of the user has swapped the primary and secondary mouse key, and, depending on the outcome, queries a system mouse state function differently.
As I have learned, even this low-level function receives the already swapped primary/secondary mouse. No need to check myself.
The code is used in the code that differentiates between left+click and hold and double-click, which in turn prevent you from panning the image in the Quick View Panel and Viewer. I have fixed this for the next release.
Tip: In Windows 11, you can enable this setting directly here:

Thanks Mario :) . Looking forward to the next release.
