I was using Winscp and while I close it, I got un popup whith the message:
Assertion failed: ramdon_active >=0, file putty\SSHRAND.c, line 242
and afer that Abnormal programm termination
I'm using Winscp 4.26 GUI Explorer for few days and it worked perfectly.
I'm on Windows XP SP3, 32bits.
Finally, I'm using Winscp on localhost, with is a putty/ssh tunnel to the server.
