Hello, hoping someone can help me out. I have created 4 fonts in a family, however the alignment of the baseline moves up and down when I select from different styles in Suitcase, or Mirosoft Word etc...

I have created them in FontLab, and ensured that that dimensions (decent, acent, descender, ascender etc..) across all four fonts are identical. No matter what I do they never turn out consistent though. I have opened other fonts in Suitcase and their baselines remain identical when selecting from various styles in a family. What am I doing wrong?...

Any help is REALLY appreciated.
