Problem with llMapDestination on Mac?

Hi, I'm slowly being driven mad with the llMapDestination command - its the most simple script there is yet it keeps failing; here's the gist:

string RegionName;
vector Vectors;

touch_start(integer num_detected)
{
llMapDestination(RegionName,Vectors,Lookat);
}

The script receives the region and vectors via a linked message and assigns it accordingly. Clicking on the object brings the map and the correct location up - perfect. But, if I send it a new location and click on it, the map stays the same - it doesn't change.

Now if I log out and in again - it changes. But then won't change anymore unless I log out again.

Has anyone else had the same problem? If so - what was the solution?

Your help is appreciated!

llMapDestination on Macs have been super buggy for years, going through fixes and new bugs every once in awhile the few times its even addressed... best to just not use it.... i remember back when (does it still?) it would convert all numbers to positive on Macs but keep negatives right on Windows... was annoying, and i stopped even trying to mess with it. Luckily its pretty rare someone tries to use it.
