This code was commented out but enabling it leads to no issues AFAICS and improves the usability of WINGs applications. The motivation for this patch comes from the need of distinguishing where the cursor is in the WINGs-based application which handles the database of my comics collection. This changes the behavior in all parts of wmaker where there is a text field entry, e.g. in the settings panel of dockapps. There should be no issues with a blinking cursor in such cases though...
