Some hardware glitches also showed up, including with the Microsoft wireless keyboard, some wireless cards and DataCADs Hardlock driver. LaCie has issued new drivers to allow SP2 machines to connect to hard drives with a FireWire 800 interface. "I can already see that there are tons of kinks that need to be worked out," commented one user in a Weblog posting. However, most users who mentioned one of these problems said they hadnt had any other issues.Many of the conflicting applications, such as Skype and Radio Userland, have run afoul of SP2s tightened-up policies for Internet ports, but some users said the difficulties made them feel more secure. "I had to actually put some effort in to get Timbuktu (a remote management program) punched through (it uses several ports for different features), but that was the only significant issue," said author Glenn Fleishman in response to a blog post by Microsofts Robert Scoble. "The fact that I couldnt see the machine, I liked."One developer noted that SP2 changes the way Windows allows Remote Desktop connections, used for remotely administering clients. By default, Windows Firewall blocks remote desktop connections (TCP 3389), even if the system was configured to allow them before SP2 was installed. Among other quibbles were the lack of improvements to Internet Explorer, with support for PNG graphics, Cascading Style Sheets, tabbed browsing and page rendering speed "at a standstill," according to one user. In isolated cases, users found SP2 caused serious problems for some machines, slowing down performance, making a machine unusable or failing to install at all; one user claimed to have tried installing SP2 using four different methods, but had to uninstall it each time. Most users, however, have said they had a positive experience overall with the update, with particular favorites being the popup blocker in Internet Explorer, the Security Center and improved integration of wireless technologies such as Wi-Fi and Bluetooth. "One thing that I havent heard anyone mention is the new wireless networking interface," said one user. "That has impressed me the most."
