Moving block from one column to another did not work (in homebox settings)

Hello,

I came across a glitch last night with homebox. Essentially, moving a block from column 1 to column 4 did not work even after saving the page. Steps to repro are as follows:
- Go to mysite/admin/settings/homebox/yourhomeboxpage
- Move one block from column 1 to column 4 if you have 4 columns on your page
- Save
- Once saved, go back to page
Result: my block is still in column 1.
I tried to clear the cache but that did not work. Even after disabling and re-enabling the block into column 4, the block stays in column 1.
I also tried with a similar block (list of ubercart products) and it worked fine. So, I am not sure.
Any help would be more than appreciated.
Thanks
T
