NOTE: This was originally posted as build 7440, but has since been updated to build 7441.
This new beta build just fixes a few small things since the previous one (build 7433). We’re almost ready for the final release!
To get this update, make sure you have "Also check for pre-release (beta) versions" enabled in Settings, and then click on the Check Now button. (Unfortunately alpha/beta releases are not currently available for the Microsoft Store version of the app).
Changes since 4.2.11 beta build 7433:
- Fixed: "Open Containing Folder" now selects the item in the Explorer window
- Fixed: Saving with the HEIC file type is no longer limited to a max Quality value of 90. This limitation was in place because of a crash due to heap corruption, which no longer happens.
- Fixed a bug where the selection would disappear forever if the canvas was scrolled away from it
- Fixed errors when trying to save into certain cloud-sync’d folders, e.g. OneDrive for Business. This was done by disabling the use of NTFS Transactions.
Enjoy!

Thank you for the update c:
Interesting about NTFS transactions and OneDrive. Are the two just incompatible completely, or was it just easier to turn off transactions to solve whatever issue was being hit with OneDrive?
I’m not really sure. There must be something weird that OneDrive does but I don’t have anything beyond nebulous conjecture.
However, since Microsoft has deprecated NTFS Transactions anyway, I just didn’t think it was worth the compatibility cost. A fallback code path exists anyway for non-NTFS locations, and it hasn’t shown any problems over the years, so it seemed reasonable to go 100% with it.
Thanks. I did a bunch of extra reading on them after this post (was aware of them previously, but hadn’t had to ever use them in anger). I saw the deprecation info in the documentation so felt happy to not have learned more about them previously – missed the train that derailed 🙂
