[Rd] post-installation startup problem with 2.10.0

I've just installed R2.10.0 v50082, and found the problem described below the first few times I launched it. Did not occur with v49613 (the previous most recent version I have). The problem has now gone away, and is therefore non-reproducible, but there seems to be something up with parameter processing or environment variable checking or loading of .RData files immediately after installation. Just thought you'd like to know.

I always start R in the same folder, where there's a ".RData" file that contains a '.First' function whose first lines are as follows:

function( skip.First=Sys.getenv( 'NOFIRST') != '') {
  if( skip.First) { # useful for command line startup when bugs in .First
    cat( 'Skipping .First\n')
return( invisible( NULL)) }
When I launched v50082 (simply by changing the path of R in the Windows "properties" box-- no other changes to what I normally do), it printed the "Skipping .First" message-- so '.First' was running, but deciding to abort. However, the NOFIRST environment variable was definitely not set. The other R versions that I have installed (latest v49613) didn't skip .First when launched in exactly the same way.

I modified the .First to first-of-all print 'skip.First', called 'save.image()', tried it in my other R versions, and relaunched v50082. This time, everything worked. I took out the print line, saved again, and relaunched v50082. Everything still worked! And has continued to since.

System info below-- the search path is of course what results _after_ '.First' has run, so it would have been different when I was having problems.
