Hello. I have two problems in the game. The first one is that some of the monsters cannot not be properly shown. Some of them are even invisible in my screen. I can only search them with the mouse, or look for the trace when they move or attack. Monsters with the problem include retrode series, shufflebots, howlitzer series, zombies and jellies with small sizes.

Another one is that my actions in the game are sometimes being 'delayed' after a great lag. In one similar situation, I was on the party bottom in my screen but not to the party members. The bottom was also not pressed for a long time. Once my friends described my action they saw during the issue, I recognized that the actions were those I had done for a while before that time. As for what I can see about my partners, some of the fragments of their movements (for example, one slash as a fragment) in a region are shown quickly once I reach there, and the actions of my partners are shown normally in my screen after a while.

I have re-installed the game and updated JAVA but they are still existed.

Following is the details of my computer:
Operating System: Windows XP
Processor: Intel(R) Pentium(R) 4 CPU 3.00GHz (2CPUs)
Memory: 894MB RAM
Video card: VIA Chrome9 HC IGP Family
Video Memory: 128.0 MB

Please can anyone help me?
