Dimmable CFL - flickering at the top end of brightness? (post #206919)

I have recently installed a CFL compatible dimmer with compatible/dimmable CLF bulbs.  I am having an issue because when they are at the highest brightness, the bulbs flicker.  If I drop the brightness a little from the top, they stop.  Is this an issue with

a) the dimmer switch

b) the bulbs

c) the fixture

NOTE : all CFL's are dimmable bulbs and the dimmers is CFL compatible.
Thanks in advance.

Pretty much all dimmable CFLs flicker, unfortunately.  I'd suggest you replace them with dimmable LEDs.  Not really worth fooling with dimmable CFLs anymore.

I wish I could, it is just too expensive still.  I have a fixture with 5 lights.  At $20 per light, that is way crazy.

The CFL compatible dimmers I've installed are tuneable via a small dial on the side of switch, accessible from the front, under the cover plate (instructions came with the switch).  Once I tuned them all I haven't had much of a problem.

Installing a single incandescent lamp in the bunch may help.

Thanks for the input. 

There is no input on this or the other CFL dimmer I bought.  Looked at both of them closely and nothing.

Adding the incadescent bulb helped, but there is still some shimmering.
