Perhaps there was a bug in 0.99.0 that caused it not to display the TCP options correctly for your particular trace?  (The code to display TCP options has been in Ethereal/Wireshark for a long time, so it's not that 0.99.0 can't display TCP options.  There might be *particular* TCP options that it doesn't know about, but it should at least be able to display them as raw data.)

The current version of Wireshark on *ALL* platforms is 1.2.6; 0.99.0 - and even 0.99.6! - are very old (0.99.0 dates back at least 3 years - it's so old that it wasn't even called "Wireshark" then, it was still "Ethereal").
