In two or more years this isn't fixed. What a shame.
If you're wondering what I'm talking about its the MP3 playing potentials of mIRC. The problem is that this function always crashes in Windows 98SE, and probobly win98 (first edition) and win95. Windows 95 users may be enough to count on your fingers but they do exist. And let's not forget that maybe microsoft has stopped win98 development and it is off the market it is still in massive use.
And there is the problem that in the newer windowses (2K, ME, XP, 2003) it crashes on unsupported quality encriptions of mIRC. the problem is not big, but crashing is not something users want.
