Hello there. I recently noted that there was an update to the old-school Nvidia-keyboard issue thread saying that nviewfix was outdated and to update JTFE. I've had my nvidia desktop manager disabled for a long time because I prefer winamp and can't use it properly with Nvidia enabled (the nviewfix didn't solve the issue, if I recall). So I updated my JTFE to 1.04 and enabled nvidia desktop manager, and amazingly, things seemed to work just fine.
However, upon further inspection, I found two issues. The first is most likely a compatability issue that you may just tell me I have to "deal with": I have another plugin (that for the life of me, I couldn't tell you the name of, because I can't find it on winamp.com or in my winamp prefs menu - unless it was one of those former plugins that because integrated into winamp proper: It allows you to set the number of seconds "left" and "right" on the kb will skip you. I have it set to 2 seconds either way. With the nvidia JTFE checkbox checked, it no longer skips 2 seconds, but seems to skip about 6 at a time (when I did "10" seconds, it skips about 30 - so a 3x multiplier it seems). Unlike how it usually is, I can actually see it quickly skip a few numbers at a time. This is a bit of a pain
The more major issue came after JTFE subsequently notified me that 1.05 was out and that I should update (which I did). I have reverted to 1.04 and am testing if it also occurs in that release, because it takes some time to occur: after some period of use, winamp seems to become "overloaded" and keys cause winamp to flicker a bit... keys like ctl+p - if I press it repeatedly - 3 or 4 times, I can sometimes get prefs to appear. This seems to be an issue that develops by keeping winamp open too long (not that long though - this happened in under an hour).
I'll let you know if 1.04 does the same thing. It's resulted in my dropping back to disabling nvidia, which sucks, cause I really do enjoy their desktop tools.
Edit to add: I'm not 100% sure I was on 1.05 after the update - I assumed it was simply the next version, and 1.05 DOES sound familiar, but if later versions are out (that I see now), I could be mistaken...
