for some reason, i cant change the font on the left sidebar of my mirc (6.03) from this strange font that i cant read, ive(obviously) tried going to options>font blahblah, but it will not change it
I'm not totally sure what you mean by the "left sidebar", but i think you mean you have the switchbar (where it lists what channels etc you have open) on the left and the font there is mucked up? Have you downloaded anything that alters the switchbar or mIRC's appearance in any way (like a dll) ?
If it is just standard plain-jane mIRC then the font can't be changed. If you are using Win XP and the font looks too blurry then you'll need to simply turn 'font smoothing' off.
I think Win ME may have the "smooth edges of screen fonts" feature too, but I am not sure. You would need to check in: Display Properties (right-click desktop) - "Appearance" Tab - "Effects" button - Second check box labelled "Use the following method to smooth edges of screen fonts". If it's ticked then untick that second checkbox then OK then OK again and try mIRC.
NOTE: Aside from that the font cannot be changed in the switchbar buttons in any version of Windows. If Win ME doesn't have what I described above then I am not sure what might be causing your problem.
