PROBLEM: Tags Plugin behaves like there were no tags file:

The command (clicked in the menu) "Tag Stack" shows only an empty window, though I:
- did run ctags on my .php file which did produce 'tags' with approrpiate content
- did set in the plugin option Tag Index File Paths to "tags" and "C:\myphpproject\tags"

Why is that? It seems it completely ignores the file. The activity log says:

[debug] TagFiles: added tag file: TagFile path=C:\myphpproject\tags, enabled=true, currentDirIndexFile=false
[debug] TagFiles: added tag file: TagFile path=tags, enabled=true, currentDirIndexFile=true
[debug] TagsOptionsPanel: [x] C:\myphpproject\tags
[debug] TagsOptionsPanel: [x] tags

What's wrong/how to find it out? Thank's for any advice! Kuba
