When I right click on the FX bin, usually the "Audio FX" part, when scrolled over, shows your plugins (or folders if a custom layout).  Now, out of the blue, there is no submenu to scroll over.  Instead, I have to click on Audio FX for it to bring up the plugins/folders.
 
Anyone else seeing this?  Very odd - not a dealbreaker, certainly, but I'm hoping I'm not the only one and it's not indicativfe of a bigger problem simmering under the surface.
 
Thanks.

Is this the weirdness? http://forum.cakewalk.com/FindPost/3010049

Indeed it is, thank you.  I suppose this happened when I added a "By Manufacturer" section to my custom plugin menu, that included all Waves plugins in a single folder.  I'll have to break it down.
 
I assume that's what is meant - i.e., to avoid the issue, create custom plugin menu folders containing under 500 plugins(?)
 
What the hell am I doing with 500+ plugins anyhow?
