The new mIRC 6.2 has something which might rather be a fix to an old bug (if it was a bug at all), or a bug by itself.
In old versions of mIRC, if you would have created a window with tabs (window -t10,20,30,40), and then add a line:
//aline @window 2First $chr(9) Second $chr(9) Third $chr(9) Forth
Then the 2 would only affect the tab that it was set on.
In fact, all wrapping would affect only the columns they were set on.
With mIRC 6.2 it 2 affects all that comes after it (it is not being stoped by the $chr(9) )
This would cause incompatibilities with older scripts which counted on $chr(9) breaking the wrapping.
For example You coded something that you have expected that color would return to Black after the $chr(9)
Another example is if you wanted a line to be bold then you would do:
/aline @window $chr(2) First $chr(9) $chr(2) Second $chr(9) $chr(2) Third $chr(9) $chr(2) Forth
But now this is not the case, and this would cause the columns to have Bold
No Bold Bold
All I saw in the whatsnew.txt
123.Added aline/iline/sline/etc. -t switch, forces a re-wrap of all
lines in a window that have not yet been wrapped to the current
This might be related (It talks about wrapping the whole lines), or maybe it is the cause of the bug.....
