Version: 1.5.5 (using KDE KDE 3.5.5) Installed from: Ubuntu Packages OS: Linux Sometimes, usually if when i "undo" an action the application gets very slow. I realized that is because the file got too big with no reason at all. It all happened to me while drawing sequence diagrams. i.e: the xmi file weights 30kb and a few minutes (actions) it weights 1.5mb Anyway, by checking the file file with a text editor i noted that a line appear to be repeated several times. I removed the repeated lines but the first one and the application works fast again. That has been my solution by the moment, but it's not good enough for other users. This is the repeated line i mentioned before: <UML:Stereotype isSpecification="false" isLeaf="false" visibility="public" namespace="1" xmi.id="2" isRoot="false" isAbstract="false" name="folder" />
This is a known bug in 1.5.5. Please use SVN or the latest released version 1.5.61, available from http://uml.sourceforge.net/download.php
