Can we stop messages from being centered (PT8.56/PUM26)?

We have some error messages that are a little long in our environment. For example, we have some edits on the Name field.  Previously, these messages were left justified and looked fine.  With our new environment on Fluid pages (or Classic Plus Enabled), the text is centered.  This is a little difficult to read.  We would prefer it to be left justified.

If we remove the Returns, the message is one huge long box that takes up the entire screen.  The message appears the same with MessageBox and Error MsgGet.

Any ideas???

Thanks!
