certain submission options erroneously default to post

Hi,

We have an instance loading problem on our main form when using build 1.5.4.1019. It looks like nothing is loading...
See attached screenshots for a comparison 1.5.4.1019 vs 1.5.4.1004 (which is all fine).

Please let me know if I can send you any info that might be helpful for your investigations. Regards,

Guillaume
