We made Mabimessage check if your running windows Vista then for it to see if you have service pack 2 installed as some of the things we use are only in SP2 such as the text to speech.
If you do have windows Vista with SP2 installed and see that msg then please let us know as our check might not be working for some reason on your machine.
Also if you don't have SP2 then maybe you should buy a copy of windows instead of pirating it. Because that's the only reason I could think of why someone wouldn't have SP2 installed.
I've whacked this together to monitor the times and encourage people to use mabimessage (It's only temporary till I make a nicer one and add it into Mabimessage):
If a boss was seen recently it's in black, red if it's due or over due (No one using mabimessage has seen it since the last spawn) and it goes green with the word "NOW" if it has been seen to have spawned and will stay that way for 10 mins (Which is the minimum time any boss will stay spawned, some stay longer).
A few changes we've made. The first being a skin change (We're thinking of make Mabimessge be able to have multiple skins of which you can chose from). The second is the user text filter which allows you to block lines of text containing key words like "www" and ".com" making it so you don't have to see bot spam in Mabimessage ever again.
The code used in the text filter should be easy to understand so you can edit it yourself if you fell it needs improving and you can post those improvements here if you feel like sharing.
We plan on adding a translation option to Mabimessage soon as well so you can know what those non english (or what ever your native language is) speaking people are saying. We're working on trying to get the google translation for this.
