Slow data connection

Thanks for the link <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=59640&image=1&table=forumreplies' class='bbc_emoticon' alt=':rolleyes:' />

I've been following the advice on the link and it has help loading pages but I am still having a big problem when I link to a notes page with discussions from a client. There are only 3 fields to the link table, ID, linkID & Note which is a text where I copy email and other correspondence. This table seems to sometimes load and hang with the loading.
Any advice, please <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=reply&id=59642&image=1&table=forumreplies' class='bbc_emoticon' alt=':unsure:' />

I think the problem may be with the database, I check with firebug and I get the following error;

myColumnDefs[id_cell] is undefined

[Break On This Error] {areaCodes[myColumnDefs[id_cell].key]=...e')?$(this).attr('style'):'');if(!i)
I checked the tables I there were some records with NULL values for the linkID. I deleted these records but I still get the same problem. This is happening only with one record the others are loading fine.
Can someone please explain.

Antoine,
it's not clear if you talking about slow connection or about some kind of error. In both cases providing a meaningful advice is not possible without access to your application.
I recommend to post your application to Demo Account and open a ticket at http://support.xlinesoft.com sending your Demo Account URL. 'Demo Account' button can be found on the last screen in the program.

I've managed to narrow down the problem. I deleted the discussions linked to the particular record and then started again. I removed the Rich text editor and it worked. Afterwards I added it back as a editor to the text field.
It worked fine until I copied and pasted a particular email that I had sent to a client. Once I added that record it seemed to corrupt the database. I then had to delete the record via phpmyadmin which corrected the problem.
I am very confused as to why this happens, I think it may have something to do with the table inserted in the email body.

All this is highly confusing.

How do I load a different editor like ckeditor

I managed to find the help on loading ckeditor at http://xlinesoft.com/phprunner/docs/rich_text_editor_plugins.htm
It seems that it has to do with the html coding in the text that I paste. If I paste the email using the paste as text only it accepts the record and doesn't corrupt the database.
If someone can assist further I will appreciate it as this way I loose the formatting of my messages.
