Thanks for the tip. I just found out I was passing SHCNF_FLUSHNOWAIT flag to the calls. By changing the flag to SHCNF_FLUSH, the icons are refreshed correctly (at least most of the time). Though the delay on refreshing is noticeable from one icon to the other. But that's not intolerable for now. BTW, is there any ill effect in the use of SHCNF_FLUSH? I don't understand the reason why SHCNF_FLUSHNOWAIT would not work though. I will experiment with SHCNE_UPDATEDIR to see if it help on this. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
