the subject says it all :-) I reinstalled wine (see a previous post) due to some errors I was having, and deleted anything in ~/.wine and everywhere else as per http://wiki.winehq.org/FAQ#uninstall I then reinstalled my app (Treepad), which ALWAYS worked in wine. The install goes ok, while at launch I get this: fixme:mountmgr:harddisk_ioctl unsupported ioctl 4d004 err:seh:setup_exception_record stack overflow 1084 bytes in thread 0009 eip 699f1ad7 esp 00240ef4 stack 0x240000-0x241000-0x340000 Segmentation fault (core dumped) WTF? thanks for any help... alessandro
