Have used this program for years alongside Picasa and GIMP with no problems at all.
I see ThumbsPlus and Picasa as complementary. Picasa has some indexing tricks e.g. face matching, that ThumbsPlus does not but overall can't come near ThumbsPlus.
It's a very good, stable piece of software.
Coli U. Been using this prog since it was first released and have always found it perfect for my requirements.
