You are too swift. I had all intention of writing in this thread.And in case he doesn't, BP should know about this.
As soon as I found that I lost my icons after installing MRUF-lst in a new 6.0.5 and subsequently recovered by uninstalling, I think my first obligation was to advise mosher0. Read the last line of my post to bigpup. Check the timestamps of the 2 posts. It would not have been fair to mosher0 to "accuse" his software for what I had reported. Certainly not in this thread. And certainly not before giving him a chance to respond.
There is a likelihood that because of my latest experience that it could be the reason also for the first. But I cannot categorically say so and I wont. It can be co-incidence. Maybe I was just lucky that the uninstall worked out OK. But as musher0 himself cautioned, MRUF-lst is development software so those who install it should take appropriate measures.
