In the install directory for IPB there should be a IPBOptions.cfg file. You have a couple options... one would be to delete that file (and lose any saved preferences), OR the other would be to edit it in a text editor (extremely simple).

If you open it in a text editor you should see something that resembles this:

---

[Main]
mGeomW = [#]
mGeomH = [#]
mGeomX = [#]
mGeomY = [#]

[Figure]
fDialog = [1 or 0]
fGeomX = [#]
fGeomY = [#]
who = [figure name]

[Processing]
pDialog = [1 or 0]
pGeomX = [#]
pGeomY = [#]
batchProcess = [1 or 0]
injRemBoth = [1 or 0]
injRemType = [1 or 0]
ignoreNonMaster = [1 or 0]
ignoreNonBody = [1 or 0]
ignoreNonHead = [1 or 0]
ignoreReadscripts = [1 or 0]
nonZeroed = [1 or 0]
roundEmUp = [1 or 0]
ignoreExpressions = [1 or 0]
expressOnly = [1 or 0]
ignoreZeroed = [1 or 0]
ignoreScale = [1 or 0]
readScriptOnly = [1 or 0]

[Add On]
aDialog = [1 or 0]
aGeomX = [#]
aGeomY = [#]
v3AnnaMarie = [1 or 0]
v3MorExpPak1 = [1 or 0]
v3HornPak = [1 or 0]
v3MalePak = [1 or 0]

Where you see '[#]' above, there will be numbers corresponding to the width(W), height(H), horizontal position(X) and/or vertical position(Y) of your screen (measured in pixels - 0x,0y being the top left corner). Deleting those lines will cause IPB to use default internal values. By default, the option dialogs appear with the title bar under your cursor the first time they are displayed (without specific coordinates being indicated - as they are in the config file). F2, F3 and F4 toggle the option dialogs. If a value is indicated in the config file or the dialog has been displayed since IPB was launched, the size/position of the main window and the dialogs will be dictated by the last value in memory.

Above you'll also notice the '[1 or 0]' next to many of the options. These are boolean values (1 = checked, 0 = unchecked) that set the editable options in the dialogs.

Once you have IPB configured the way you like, select 'Options -> Save Options File.' The next time you launch IPB it'll be the same size/position and have the same options selected as it did when you choose to save.
