What works

Installed on fresh wine with ies4linux (.wine in home dir linked to .ies4linux/ie6). Security Certificates exported from existing windows IE install, into ies4linux IE install. Winecfg for qw.exe set to NOT "allow window manager to control windows."

Under this setup, everything appears to work as expected. I have definitely tested the register, DirectConnect, OFX file download from website, scheduled transactions, register reconcile, and Online Banking (making payments and same bank funds transfers). All of these seem to be working as expected (with the "glitch" caveat below).

What does not

There are still some interface glitches where keyboard focus is stolen from Quicken (after accepting a "is this the scheduled transaction for xx/xx/xxxx" dialog) and passed to the next gnome window below the running Quicken. (Have not tested this with other Wine applications running)

Without winecfg "allow window manager control" setting unchecked, certain popup items (split transaction window and edit scheduled transaction window, f.ex.) go into (an apparent) repeating resize loop.

Without IE Security Certificates properly installed, Quicken would not establish DirectConnect connection with my financial institutions.

Installed on wine with Picasa and no ies4linux, Quicken would install but would crash when attempting import of Quicken backup file.

What was not tested
I have not yet testing printing, reporting, or budgeting.

Additional Comments

Keyboard focus stealing interface glitch is potentially destructive considering the "delete" key is frequently used when entering text in the Quicken register.
