I tried .4, and still same issue. At least it did not freek things out like .05 - .10 did (not sure why .05 - .10 freeks things out).

However, I did notice something else. The green light on the IR receiver stays on longer as well when using the Pronto, and I would assume it cannot receive another signal until the 1st command finishes.

So it looks as if the signal getting from the remote to the IR receiver is slower with the Pronto, and that the signal continues for a longer interval than the orriginal remote.

I hope this exra info helps.
