Ref: PWP 8.0.exe 180627 with msi 180621

I have been experiencing intermittent failure to complete a manual or script command that utilizes the MaskTool-Color Range feature when attempting an Overlay Apply... ...the display will flicker and return to the previous command view or turn gray with a crash after approx. 1 sec.. This happens inconsistently, perhaps every third time... ...otherwise execution is normal.

If there is a crash, there is a "PWP 8.0.exe.*.dmp" file generated in the CrashDumps folder.

MaskTool-BrightnessCurve "command" Overlay Apply will also do this but with less frequency.

The *.dmp files when a crash occurs are around 10MB each, would they be useful for your analysis?

Unfortunately the DMP files are not useful. The best way to find this kind of problem is for you to send me the input files and the script so I can reproduce it here. Running under the debugger usually catches problems before a crash occurs.

Script and a small and large sRGB jpg images here: http://www.l7.org/IMAGEs_by_DEN/misc/PWP8_180627/.

The small image is PWPs color hexagon and shows what the script for saturation increase does.

Addendum: Manually doing a MaskTool-ColorRange Overlay Apply seems to be the most consistent failure to execute rather then running the script.

I have also exprienced the display going gray but also the buttons in the main menu bar disappearing with only black rectangles left with the connection to using a mask tool.
It happened when I used the Mask transformation dialog and played with the mask paint tool. The PWP did not crash and when I closed the Mask transformation dialog, the preview and buttons recovered. However, after reopening the Mask transformation dialog, the New mask... command repeatedly failed to open the Mask dialog. I only flashed for a fraction of a second and disappeared.

I tried to reproduce it and was mosty successful. All I did was painting with large radius changing other setings like Spacing, Overlapping Strokes and Apply to.
This looks a bit like a memory problem. Not sure if this has the same root cause.

I have added a script that contains a MaskTool-BrightnessCurve sequence to the available download link: http://www.l7.org/IMAGEs_by_DEN/misc/PWP8_180627/ that duplicates the Color Range Mask except masking is executed using the Brightness Curve feature.

Thank you davidh for your additional input...

I did find and fix a resource leak in the Mask Paint tool for the next release.

I still sometimes crash when running scripts containing a mask_mode Overlay command after an initial mask_mode Add command.

Additionally, when forming a mask manually, mask_mode's Subtract, Overlay, and Invert do not function... ...the display blinks and reverts to the initial Add mask or sometimes crashes (sometimes when closing the mask window).

I have fixed the mask range tool not working in some modes for the next release, but I cannot reproduce a crash. If it persists, please send me the actual image it is crashing on, the script that causes the crash, and a copy of your preferences settings file.
