Besides the antivirus, also try disabling the firewall.
If you installed the 64-bit version of DipTrace, try installing the 32-bit version instead.

What operating system are you using?
When Schematics starts, try changing Graphics Mode in the main menu View, then restart Schematics.

Try temporarily rename the Data Unicode folder in `C:\ProgramData\DipTrace`.
It also contains the program settings.
After that, run the program. If the problem persists, rename the folder back.
Also try running Schematics and PCB Layout as an administrator.

There is no option in panelization for this kind of editing. As a workaround, you can try placing a Board Cutout shape in the area where you need the material to be milled out.

At the moment, no changes are planned regarding this matter.

Thank you for the report. I confirm the issue. We will fix it.
For now, to work around the problem, you can change the Line Spacing parameter for the multiline text in Properties.

At the moment, there are no plans to develop these features for the upcoming version of the program.

Thank you for the file and for the report. Yes, indeed, there is an issue with solder mask display in 3D for vias. I have created a ticket in our internal bug tracker for the developer’s review.

Thank you for the report. We will review the dimensions and make changes if necessary.

Thank you for the report. Check Net Connectivity detects this type of error, but DRC does not. I will create an issue for the developer to review.
