I am unsure at the moment on why it is so slow, there could be a few factors contributing to the performance (it could be the fact that you only have 128MB RAM, or you have a slow harddisk). In your home directory, there is a file called .vpuml.properties delete this file and try running VP-UML again. ---

I don’t know why - it likes to me. Can it do an error? Ok. I reinstall to my home directory - situation not changes. I have downloaded .bin file. ---

May I ask why VP-UML is installed in /opt directory? Is the version of VP=UML you downloaded the .bin file? or the no\_install variant? ---

My computer is AMD Athlon 1.2MHz; 128MB of RAM; 11GB of free space on disk. I have installed java sdk 1.4.2.01. VP-UML CE is installed to /opt/vpunlce Command java -cp vpuml.jar:vpumlresources.jar RV works same. Splash screen progress bar freezs on 75% for a few minutes. In this time log-file quikly grows. After this program starts up. I can draw diagramms (but works slow). But when I want close program, save diagram or open exiting diagram program is not responding… (sorry for my bad English) Thanks.

Dima, What are the specifications of your computer? Which directory did you install VP-UML CE to? Can you please test if the following command works: java -cp vpuml.jar:vpumlresources.jar RV Martyn ---

Other java-applications (NetBeans, for example) works fine on my mashine. In my home directory I found only .VPUMLCommunity.vpl and .vpumlproject.xml, which starting from “vpuml”. Removing of it not helps. ---

I have install VP for UML CE on another machine (AMD Athlon 1.4Mhz, 256Mb RAM, Mandrake Linux 9.1) It works, without any manipulations… And I have installed to /opt directory - no problem. Very strange. ---

Hello All! I have downloaded VP CE for linux (Mandrake 9.2). It starts long time (about 3min). Then, when I try to open exiting project VP hangs up. I can only kill it. In this time cpu activity is 0%. Best regards. Dima Fedotov
