If you are running an old(er) version of DSL, say older than v3.2 then perhaps you should upgrade:

Improved MyDSL download via the Lua GUI - implemented server side parsing.
Server side parsing makes for a faster selection list and is also much less complex on the client side.Ah. Ok guys. It's most propably because of my old DSL. I need to burn a new version.
Thanks for help. I too have had this problem and jpeters also reported it in a thread titled "UCI area" in the "myDSL Extensions > Apps" forum, dated Feb. 4. I've tracked down the source of the problem and posted about it in that forum under the title "MyDSL UCI problem / solution."Does no one much good to download and use, then report issues that have since been fixed. V2.2 is quite old.
