I have a similar issue running on a Windows 2008R2 IIS 7 with with PHP 5.3 and WordPress 3.4.1.
I have about 20 tables which all work perfectly fine, and one table with over 166 rows. The same table used to work fine on my Windows 2003 II6 server.
At row 166 the last few columns on the table are not visible and use JavaScript library checkbox cannot be clicked on
I searched in PHP.ini for Suhosin but it does not appear and as I’m running IIS and not apache, there is no /etc/php5/apache2/conf.d/suhosin.ini, nor a suhosin.ini anywhere on the system.
Any ideas of what to adjust to fix this on a windows server?
