I am using SlickEdit Version 15.0.1.3 with the latest hot fixes.
Something I have noticed for a long time, the documentation says that tabs for files with same name but different extension would show only only tab with the full name and the rest with just the extension.
While this works for source code, such as .c and .h, files, it does not appear to work for non-source code files, like .mak and .prm.
I have attached a screen picture to show this.
