| TextAnalyser.Get(n, maxchars) may overwrite it's heap block. | Cause: The buffer allocated wasn't large enough. The overwrite happens when maxchars characters are read.

| Venom's Select Case statement failed with > 255 cases. | Cause: The number of cases was stored in an 8-bit value Workaround: Use multiple Select Case statements and If/Else to pre-select them. Fixed: Yes - ask for pre-release with the fix. In previous versions: Yes |
| FTPServer doesn't work fully with FileZilla | FileZilla: if multiple files are sent in one drop, sometimes a file is truncated. [Note: in order to work with Venom's FTPServer object FileZilla requires multiple FTP server tasks & objects - see Code snippets for how to deal with this.] Cause: ? Workaround: Use command line FTP in Windows or Linux, or only send one file at a time. Fixed: No. In previous versions: Yes |
