Hi, OS: windows XP SP2 browser: firefox 2 ImageUploader applet version:2.0.79.0 Just after the applet is loaded, it seems to perform a scan of the folder that freezes the user interface during a long time and take 99%CPU. Is it possible to avoid such a file analysis in order to avoid freezing. I tried to remove filter mask constraint and file size limit but this has no effect. the url of my web page is http://www.imaload.com/aurigma/index.phpBest regards, Daniel the param are: Code:iu.activeXControlCodeBase = "aurigma/ImageUploader4.cab";
iu.activeXControlVersion = "4,0,63,0";
iu.javaAppletCodeBase = "aurigma/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "2.0.79.0";
iu.showNonemptyResponse = "off";
iu.addParam("PaneLayout", "ThreePanes");
iu.addParam("FolderView", "List");
iu.addParam("TreePaneWidth", "220");
iu.addParam("FolderPaneShowDescriptions", "false");
iu.addParam("DescriptionsReadOnly", "true");
iu.addParam("ShowButtons", "false");
iu.addParam("ShowDebugWindow", "false");
iu.addParam("EnableRotate", "false");
iu.addParam("AllowMultipleRemove", "true");
iu.addParam("BackgroundColor", "#666666");
iu.addParam("FileMask", "*.*");
iu.addParam("MinImageWidth", "0");
iu.addParam("MinImageHeight", "0");
iu.addParam("FilesPerOnePackageCount", "1");
iu.addParam("AutoRecoverMaxTriesCount", "3");
iu.addParam("AutoRecoverTimeOut", "1");

Hello,
U have checked your site and found a lot of JavaScript code in event handlers. I think the most of CPU processing is taken with these handlers. Check it, please.
Also note that while calling the first method LiveConnect (which is used for Applet to JavaScript communication) initializes its internal content so CPU is loaded for few seconds. |
