I had a problem with one type of blade and so I sent Bosch a message and received the reply today. You may find it interesting and save you from buying blades that do not work correctly. I would suspect that this is true of the 1590 as well. Below is the correspondence. I do not know it there are any other blades that are to thick to work properly or not.

Comments: I ordered a Bosch 1591 Jigsaw from Amazon and just got it
today. I cannot inset the T144BF precision wood blade that was included
because it is to wide to fit in the groove in the small roller. The
blade measures .065 of an inch thick and the groove in the roller, as
near as I can meaure it, is .054 of an inch. Is the blade defective or
is the roller to narrow? The T123X (.039") and the T244D (.049") work
fine as well as the T101BF blades that I bought from Home Depot. I have
two packages of 101AQ blades ordered and do not know if they are to
thick to work or not.

Thank you for writing and for your patience. These blades are new and
are thicker than our older blades. The rollers
on the saws are in the process of being changed and will have a wider
groove. This will be a running change so I don't know exactly when this
will take place.
In the meantime, after a short running period the rear of the blade
"will" conform itself to the current roller and work fine.
I do apologize for any inconvenience this may cause.
Please let me know if there is anything more I can help you with.
