Not TLB related, but you might be able to help. :)

Well, since you disqualified my two responses to your first question, I'll tackle this one:

P.P.S: are tooltips supposed to appear when the cursor is over the netmon icon (as seen on the netmon page)?

Yes, but only if you have tooltips enabled.

Yuri: in the process of documenting the steps required to check my above statement, I've noticed a bug. Neither of the 2 options for tooltips under other options (show tooltips on menu and tooltip style) seem to have any effect on tooltips whatsoever. On my toolbars that have tooltips disabled, I can't re-enable them, and on menus that have them enabled, I can't turn them off, nor can I change the style. The changes are reflected in the setup.ini file, but they don't show up on the toolbar.

So Denis: if your tooltips aren't working on your tlb, try creating a new toolbar and putting your netmon there, to see if that works.
