Some versions back, I reported on a problem that occurred when using the mouse wheel while working in the Tag Panel. Sometimes, rolling the wheel when the pointer overlays a field's value, the value would change from the previously entered (and already written) text to
<blank>. This behavior easily goes unnoticed, which is a serious issue.. The result is that further tag panel operations end up removing desired values from the affected field(s).
The problem was promptly fixed after I first reported it, but it appears that it has crept back into the code. It's the only way I can explain the fact that once-written tags disappear mysteriously, causing us to either (1) unknowingly omit critical metadata at completion, or (2) re-entering the tag field's values all over again.
Please make sure the mouse wheel is disabled when the pointer is in the body of the tag panel. Of course it would be nice if it still operates when the pointer is in the scroll bar region.
