Description of the bug

During creation of a new checking account I attempted to change the Currency from my default "Euro" to "United States dollar" (or other, also reproduced with CHF). After closing the selection with "Select", I can still see the "Edit Account" dialogue with several "Invalid Amount" messages (see screenshot). At the same time MMEX crashes (Debug report window openes). Unfortunately also debug report window is frozen, so I need to kill MMEX.
After reopening MMEX it seems that account was created anyhow.

Reproduction

Is the bug reproducible?

• Always
• Randomly
• Happened only once

Reproduction steps:

1. Start to create new checking account
2. Change currency to "United States dollar" and press "Select"

I was not able to reproduce it with a new empty database.

Expected result:
Further account settings can be made after changing currency and after "OK" account is created without crash.

Actual result:
Crashes after changing currency.
