My icon first calls a batch file which sets an environment variable and calls foxprox.exe. The batch file property sheet doesn't show any any autoexec.nt or config.nt files, but for foxprox.exe they show the following (default values):

autoexec.nt
lh \winnt\system32\mscdexnt.exe
lh \winnt\system32\redir
lh \winnt\system32\dosx
\winnt\system32\vipx.exe
\winnt\system32\vlmsup.exe

config.nt
dos=high,umb
device=\winnt\system32\himem.sys
files=125

I tried limiting the memory use of foxprox.exe to 16MB, but it uses all memory(192MB) and becomes slow (because of paging?).

Thanks for your help.
