Hi to all, After I tried with several text editors, in several different PC and laptops, the problem persist. I talked with another guy in Rome who has the same problem, and he is the only BioC-WinXP user I know... With windowsXP, once I installed and LOADED samr or pamr packages, all the error messages appear in a pop-up window. This doesn't happen with all the other packages, as far as I tried. When you have a big workspace, there is a delay between the hit "RETURN" and the appearing of the pop-up info window (with the error message inside) to clic-in to proceed. Bigger is the workspace, bigger is the delay (until 20-30 secs). So if you mistype or whatever, you have to wait. If you just run a script or a proc and you forgot to load a library, you have to wait 20 seconds every error of the script, clic on the "OK" button and wait for the following error. So is really impossible to work. I was using RwinEdt, and so I was thinking was his fault, I switched to Xemacs, and is the same. Also without editor at all, using Rconsole, is the same (in SDI and MDI mode). I changed PC (home, laptop, other collegue's), different installed programs, and this doesn't change. I a new R installation I installed only pamr package, nothing else, and problem is always there I don't know If this can be an useful information, but once I installed and loaded pamr or samr and I got the problem, even if I detach or remove the package, the problem remains. If I'm not wrong, with an old pamr version everything was fine. Really I have no clue (tcltk ? Pam or Sam Graphs? I don't think...), but what I know is that without loading pamr and samr everything works perfectly. The point is that I need PAM and SAM analysis, because I think that both are really useful and well done. I cannot switch directly now on linux OS, and so I have to use the Excel versions (...and yes, I tried also in a PC without excel at all, and the problem is aaalways there) and give it up to BioC... Sorry if I bother you, thanks Giulio.

Hi Giulio, The problem you are describing sounds very strange. I have a few suggestions: 1. Post to the list a recipe for reproducing the problem. Can you provide a set of commands that when entered at the R prompt produce the issue your are seeing? 2. Include the output of sessionInfo() 3. You might also try to find an old version of pamr and see if the error goes away. You may also want to contact the package maintainers (with above detail) directly. Best, + seth
