A quick heads-up for anyone using Directory Opus and MaxTo together.
If you have both installed on the same system and have had Opus crashing or spontaneously exiting, especially when the image viewer opens, then it is possible MaxTo was the cause.
Unfortunately, we don't know of anything which we can do on our side to mitigate the problem or block the MaxTo hooks/DLL from loading into the Opus process. It is something which MaxTo will need to fix, either by fixing the code which is crashing or by adding Opus to their compatibility list (similar to the way it avoids affecting other software to prevent causing similar issues with things like the Windows Terminal app).
