    ACR 4.4.1 not Compatible with CS and CS3

      ACR 4.4.1 (and beta4.5) does not work properly on a Windows XP Pro (SP2) computer with both CS and CS3 installed. A Raw file from Pentax 1stDS (.PEF) opened in CS3 through ACR 4.4.1 shows a black thumbnail in the History palette beside the file name. Conversion of the file to Lab Color shows a black image. ACR beta 4.5 shows the same behavior. No version of ACR subsequent to 4.3.1 have worked properly on the Windows computer with CS and CS3 installed. Versions of ACR subsequent to 4.3.1 and prior to 4.4.1 had other idiosyncrasies.
