With a text editor open and read (only) your Prefs.js file. Look for entries that display a specific path name on your computer. Those paths may not exist on your tablet, that is why installing SM on the memory stick may resolve your problem. Installing SM on the memory stick forces SM to create a default profile referencing files on the memory stick. Michael G PS.

Michael G In addition to what Michael says you should also be aware that all SD cards aren't created equal - differing IO speeds, etc., and the fact that you are using a "secure" SD card could mean that it may be doing things in the background that may also decrease it's effective speed - i.e. - encrypt/decrypt. Check the specs for your SD card and see...you may want to try a different one. -- - Rufus ___ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey

I'm certainly no expert but suspect that disk speed may be a major issue. SeaMonkeys cache is in the profile along with cookies, history, bookmarks and all the other sqlite databases so it's going to be reading and writing it frequently. The advertized write speed for that card is 20MB/s and that is probably for sequential writes of the optimal size so you are probably not getting anything close to that. At best it will be 5 times slower than you SDD and may be considerably more than that. Also running a release preview the drivers may not be fully optimized yet. I suggest downloading CrystalDiskMark (if it will run on Windows 8) and run it on the SD card and the SDD drive and compare the random read and write speeds. You could also try moving the cache back to the SDD drive to see if that makes a difference(Preferences-Advanced-Cache-Cache Folder Location) Jim ___ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey

What we are looking for is a reason for SM to load slowly in respect to being installed on a tablet, or PC. Look carefully at the copied version of your profile, use a common text editor, to view only, your Prefs.js file. The Preferences file will point specific loading preferences toward local files. If these files are not present at loading SM, SM will by default try and create them for launch, failure to create default files and preferences may lead to frozen SM. What I am trying to get you to do is make a very careful analysis of the profile you are copying, and make sure all the references in that profile exist on your SD card, and that they are correctly referenced in the profile. I can tell you that I have used a USB Memory Drive to launch SM on a laptop, but there I installed SM on the USB drive, created a shortcut on the desktop of the laptop, plugged in the USB drive, and launched SM.

Good question, and I don't know the answer. Theoretically if you format NTFS and retest and performance is bad you can use the SD Formatter from the SD Association ( https://www.sdcard.org/downloads/formatter_3/ ) to format it back to Fat32 for optimal performance, but I have never done it and don't know that it would get it back to the same performance it has now. It might be worth using it to format the poor performing one back to Fat32 and retest to see if it makes a difference. That might give you a hint what you want to do with the new one. Thanks, but I decided just to stick with FAT32. SeaMonkey is working much better with the profile on the new card. -- David Wilkinson ___ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
