Well, i've used Glare for aages, but nowadays it seems to "shut itself off" once every few days, sometimes a reboot fixes it sometimes it stays this way for days. Reinstalling the plugin doesnt help. The real issue here is.. I just go to the filters menu as usual, flaming pear, then glare, and i can set all settings and see it in the preview window fine, but as soon as i click "Ok" it just doesnt do anything, as if i clicked the cancel button :( Anyone have ANY idea whats wrong? used to get this problem with LunarCell as well, but not anymore

I've never had problems with the flamingpear filters. Are the Glare and LunarCell each registered?

And i've been wanting to get the glare filter, but i believe it is old right now. Flaming Pear do not seem to have it anymore.

One of flamingpear's bundles:

The Designer Sextet is a bundle six transcendent plugin filters to warp, recolor, abuse and dreamify your images. Includes Aetherize, Twist, Swerve, Lacquer, Silver, and Glare.

Try defrag before re-installation. It's probably a Windows SNAFU...

Check your Temp folder under Local Settings. I only have one FP filter (Flood),that I almost never use. But whenever I use PS,that flood filter creates a couple files and a folder in the temps even though it was not used. When I have used it, those files got pretty big,and they don't get cleared out when you shut down. Might be the same for your Glare filter. SWAMP

This probably isn't it, but might as well suggest it just in case. I find that Flaming Pear plugins don't like being applied to large images. Are you working with larger images lately?

I've had this exact problem a few times with my Melancholytron filter. Yes, it's legal and registered. :-) For some reason, it won't apply if I've been using several applications and surfing the net prior to opening Photoshop, however, if I open PS soon after booting up, there's no problem. It doesn't happen often, but is obviously frustrating when it does. A simple reboot always solves the problem, which leads me to suspect maybe it's RAM related, although that's sort of odd, considering that my computer has plenty of physical and virtual RAM available. I've seen people complain about this with the Flood filter at the PS newsgroup. One respondant said that you can get a "reset" .exe from Flaming Pear, although I have no idea what that does.
